Best Ant Killer For Lawns Buying Guide

Types Of Ant In Your Lawn

Never rush to pick an ant killer without identifying which type of ant you are dealing with.

While there are thousands of ant species on the planet, you are more likely to come across two common and most seriously problematic ones: fire ants and carpenter ants.

The former species are notoriously troublesome as they tend to gather in enormous colonies and sting painfully. Fire ants are extremely dangerous for kids and pets, causing allergies or, even worse, fatal reactions.

Moreover, they often chew through the outdoor wiring and ruin the household electrical system. Their nests are deep inside the mounds, making eliminating them quite challenging.

Carpenter ants typically inhabit wooden objects and damp areas like rotten trees and old stumps. Although this species is not harmful for humans, it can wreak havoc on your house structure and lead to underground problems.

Types Of Ant Killer

There are various methods to kill ants, including liquids, liquid barriers, granules, and baits. Each type has its unique benefits and drawbacks suitable for different ant colonies and spaces.

Liquid baits like liquid and gel often work as a sweet attractant. Easy as they might appear, using those products in cracks, small crevices, and granules are sometimes difficult.

It would be best to use a syringe to dispense the gel. However, this method is not always effective in small corners or land holes.

Granules are another popular type, containing a high level of fat and protein. These ingredients ensure that ant colonies will go away while nourishing the lawn.

Moreover, granular killers are water-resistant, so if you spread the solution before the rain, there is no need to worry about possible declination of its effectiveness.

Unlike the two above ant killer types, aerosols and liquid sprayers work as an ant deterrent. By spraying the solution onto the ant trail, house corners, or gardens, you will surely keep the ants at bay.


Safety is of utmost priority, so when purchasing an ant killer product, never forget to read the instructions and its ingredients list carefully.

If you have small children and pets around, you need to make sure that your pick is a child-safe ant killer. Kids and pets may accidentally eat stray granules and unhealthy bait blocks on the ground.

Besides, you may want to avoid products with harmful ingredients as much as possible. Toxic chemicals can be washed away after the rain and cause unwanted contamination to the surrounding area, especially when the solution spreads on a slope in your garden.

Concerning the safety issues, traps are the safest choice thanks to their self-package. They are well kept inside a plastic container or protective gear, reducing the chance of pets and small kids coming in contact with the poison.
